FIDO2 WebAuthn Multifactor Authentication

WebAuthn is an API that makes it very easy for a relying party, such as a web service, to integrate strong authentication into applications using support built in to all leading browsers and platforms. This means that web services can now easily offer their users strong authentication with a choice of authenticators such as security keys or built-in platform authenticators such as biometric readers.

Support is enabled by including the following module in the WAR overlay:

<dependency>
  <groupId>org.apereo.cas</groupId>
  <artifactId>cas-server-support-webauthn</artifactId>
  <version>${cas.version}</version>
</dependency>

implementation "org.apereo.cas:cas-server-support-webauthn:${project.'cas.version'}"

dependencyManagement {
  imports {
    mavenBom "org.apereo.cas:cas-server-support-bom:${project.'cas.version'}"
  }
}

dependencies {  
  implementation "org.apereo.cas:cas-server-support-webauthn"
}

The following settings and properties are available from the CAS configuration catalog:

_{The configuration settings listed below are tagged as Required in the CAS configuration metadata. This flag indicates that the presence of the setting may be needed to activate or affect the behavior of the CAS feature and generally should be reviewed, possibly owned and adjusted. If the setting is assigned a default value, you do not need to strictly put the setting in your copy of the configuration, but should review it nonetheless to make sure it matches your deployment expectations.}

cas.authn.mfa.web-authn.core.trusted-device-metadata.location=

The location of the resource. Resources can be URLS, or files found either on the classpath or outside somewhere in the file system.

org.apereo.cas.configuration.model.SpringResourceProperties.

cas.authn.mfa.web-authn.core.application-id=

The extension input to set for the appid extension when initiating authentication operations. If this member is set, starting an assertion op will automatically set the appid extension input, and finish assertion op will adjust its verification logic to also accept this AppID as an alternative to the RP ID. By default, this is not set.

org.apereo.cas.configuration.model.support.mfa.webauthn.WebAuthnMultifactorAuthenticationCoreProperties.

cas.authn.mfa.web-authn.core.relying-party-id=

The id that will be set as the rp parameter when initiating registration operations, and which id hash will be compared against. This is a required parameter. A successful registration or authentication operation requires rp id hash to exactly equal the SHA-256 hash of this id member. Alternatively, it may instead equal the SHA-256 hash of application id if the latter is present.

org.apereo.cas.configuration.model.support.mfa.webauthn.WebAuthnMultifactorAuthenticationCoreProperties.

cas.authn.mfa.web-authn.core.relying-party-name=

org.apereo.cas.configuration.model.support.mfa.webauthn.WebAuthnMultifactorAuthenticationCoreProperties.

cas.authn.mfa.web-authn.crypto.encryption.key=

The encryption key is a JWT whose length is defined by the encryption key size setting.

org.apereo.cas.configuration.model.core.util.EncryptionJwtCryptoProperties.

cas.authn.mfa.web-authn.crypto.signing.key=

The signing key is a JWT whose length is defined by the signing key size setting.

org.apereo.cas.configuration.model.core.util.SigningJwtCryptoProperties.

_{The configuration settings listed below are tagged as Optional in the CAS configuration metadata. This flag indicates that the presence of the setting is not immediately necessary in the end-user CAS configuration, because a default value is assigned or the activation of the feature is not conditionally controlled by the setting value.}

cas.authn.mfa.web-authn.core.allow-primary-authentication=false

Configure the authentication flow to allow web-authn to be used as the first primary factor for authentication. Registered accounts with a valid webauthn registration record can choose to login using their device as the first step.

org.apereo.cas.configuration.model.support.mfa.webauthn.WebAuthnMultifactorAuthenticationCoreProperties.

cas.authn.mfa.web-authn.core.allow-untrusted-attestation=false

If false finish registration op will only allow registrations where the attestation signature can be linked to a trusted attestation root. This excludes self attestation and none attestation. Regardless of the value of this option, invalid attestation statements of supported formats will always be rejected. For example, a "packed" attestation statement with an invalid signature will be rejected even if this option is set to true.

org.apereo.cas.configuration.model.support.mfa.webauthn.WebAuthnMultifactorAuthenticationCoreProperties.

cas.authn.mfa.web-authn.core.allowed-origins=

The allowed origins that returned authenticator responses will be compared against. The default is set to the server name. A successful registration or authentication operation requires origins to exactly equal one of these values.

org.apereo.cas.configuration.model.core.util.EncryptionJwtSigningJwtCryptographyProperties.

This CAS feature is able to accept signing and encryption crypto keys. In most scenarios if keys are not provided, CAS will auto-generate them. The following instructions apply if you wish to manually and beforehand create the signing and encryption keys.

Note that if you are asked to create a JWK of a certain size for the key, you are to use the following set of commands to generate the token:

wget https://raw.githubusercontent.com/apereo/cas/master/etc/jwk-gen.jar
java -jar jwk-gen.jar -t oct -s [size]

The outcome would be similar to:

{
  "kty": "oct",
  "kid": "...",
  "k": "..."
}

The generated value for k needs to be assigned to the relevant CAS settings. Note that keys generated via the above algorithm are processed by CAS using the Advanced Encryption Standard (AES) algorithm which is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology.

Configuration Metadata

The collection of configuration properties listed in this section are automatically generated from the CAS source and components that contain the actual field definitions, types, descriptions, modules, etc. This metadata may not always be 100% accurate, or could be lacking details and sufficient explanations.

Be Selective

This section is meant as a guide only. Do NOT copy/paste the entire collection of settings into your CAS configuration; rather pick only the properties that you need. Do NOT enable settings unless you are certain of their purpose and do NOT copy settings into your configuration only to keep them as reference. All these ideas lead to upgrade headaches, maintenance nightmares and premature aging.

YAGNI

Note that for nearly ALL use cases, declaring and configuring properties listed here is sufficient. You should NOT have to explicitly massage a CAS XML/Java/etc configuration file to design an authentication handler, create attribute release policies, etc. CAS at runtime will auto-configure all required changes for you. If you are unsure about the meaning of a given CAS setting, do NOT turn it on without hesitation. Review the codebase or better yet, ask questions to clarify the intended behavior.

Naming Convention

Property names can be specified in very relaxed terms. For instance cas.someProperty, cas.some-property, cas.some_property are all valid names. While all forms are accepted by CAS, there are certain components (in CAS and other frameworks used) whose activation at runtime is conditional on a property value, where this property is required to have been specified in CAS configuration using kebab case. This is both true for properties that are owned by CAS as well as those that might be presented to the system via an external library or framework such as Spring Boot, etc. When possible, properties should be stored in lower-case kebab format, such as cas.property-name=value.S ettings and properties that are controlled by the CAS platform directly always begin with the prefix cas. All other settings are controlled and provided to CAS via other underlying frameworks and may have their own schemas and syntax. BE CAREFUL with the distinction. Unrecognized properties are rejected by CAS and/or frameworks upon which CAS depends. This means if you somehow misspell a property definition or fail to adhere to the dot-notation syntax and such, your setting is entirely refused by CAS and likely the feature it controls will never be activated in the way you intend.

Validation

Configuration properties are automatically validated on CAS startup to report issues with configuration binding, specially if defined CAS settings cannot be recognized or validated by the configuration schema. The validation process is on by default and can be skipped on startup using a special system property SKIP_CONFIG_VALIDATION that should be set to true. Additional validation processes are also handled via Configuration Metadata and property migrations applied automatically on startup by Spring Boot and family.

Indexed Settings

CAS settings able to accept multiple values are typically documented with an index, such as cas.some.setting[0]=value. The index [0] is meant to be incremented by the adopter to allow for distinct multiple configuration blocks.

Discoverable Credentials

It is possible to allow WebAuthN to act as a standalone authentication strategy for primary authentication. Using this approach, user accounts and FIDO2-enabled devices that have already registered with CAS are given the option to login using their FIDO2-enabled device for a passwordless authentication experience.

Discoverable Credential means that the private key and associated metadata is stored in persistent memory on the authenticator, instead of encrypted and stored on the relying party server.

Device registration can occur out of band using available CAS APIs, or by allowing users to pass through the registration flow as part of the typical multifactor authentication. See below for details on device registration.

Registration

Device registration flows are baked into CAS automatically. A background cleaner process is also automatically scheduled to scan the repository periodically and remove expired device registration records based on configured parameters. In the default setting, devices expire after a fixed period since a user registered their device.

The following settings and properties are available from the CAS configuration catalog:

cas.authn.mfa.web-authn.cleaner.schedule.enabled=true

Whether scheduler should be enabled to schedule the job to run.

org.apereo.cas.configuration.model.support.quartz.SchedulingProperties.

cas.authn.mfa.web-authn.cleaner.schedule.enabled-on-host=.*

Overrides SchedulingProperties#enabled property value of true if this property does not match hostname of CAS server. This can be useful if deploying CAS with an image in a statefulset where all names are predictable but where having different configurations for different servers is hard. The value can be an exact hostname or a regular expression that will be used to match the hostname.

org.apereo.cas.configuration.model.support.quartz.SchedulingProperties.

cas.authn.mfa.web-authn.cleaner.schedule.repeat-interval=PT2M

String representation of a repeat interval of re-loading data for an data store implementation. This is the timeout between consecutive job’s executions.

This settings supports the java.time.Duration syntax ^[?].

org.apereo.cas.configuration.model.support.quartz.SchedulingProperties.

cas.authn.mfa.web-authn.cleaner.schedule.start-delay=PT15S

String representation of a start delay of loading data for a data store implementation. This is the delay between scheduler startup and first job’s execution

Cleaner Usage

In a clustered CAS deployment, it is best to keep the cleaner running on one designated CAS node only and turn it off on all others via CAS settings. Keeping the cleaner running on all nodes may likely lead to severe performance and locking issues.

Actuator Endpoints

The following endpoints are provided by CAS:

The following settings and properties are available from the CAS configuration catalog:

cas.monitor.endpoints.jdbc.password-encoder.encoding-algorithm=

The encoding algorithm to use such as MD5. Relevant when the type used is DEFAULT or GLIBC_CRYPT.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.password-encoder.type=NONE

Define the password encoder type to use. Type may be specified as blank or NONE to disable password encoding. It may also refer to a fully-qualified class name that implements the Spring Security's PasswordEncoder interface if you wish you define your own encoder. The following types may be used:

NONE: No password encoding (i.e. plain-text) takes place.
DEFAULT: Use the DefaultPasswordEncoder of CAS. For message-digest algorithms via character-encoding and encoding-algorithm.
BCRYPT: Use the BCryptPasswordEncoder based on the strength provided and an optional secret.
SCRYPT: Use the SCryptPasswordEncoder.
PBKDF2: Use the Pbkdf2PasswordEncoder based on the strength provided and an optional secret.
STANDARD: Use the StandardPasswordEncoder based on the secret provided.
SSHA: Use the LdapShaPasswordEncoder supports Ldap SHA and SSHA (salted-SHA). The values are base-64 encoded and have the label {SHA</code> or {SSHA</code> prepended to the encoded hash.
GLIBC_CRYPT: Use the GlibcCryptPasswordEncoder based on the encoding-algorithm, strength provided and an optional secret.
org.example.MyEncoder: An implementation of PasswordEncoder of your own choosing.
file:///path/to/script.groovy: Path to a Groovy script charged with handling password encoding operations.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

The database user must have sufficient permissions to be able to handle schema changes and updates, when needed.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.password-encoder.character-encoding=UTF-8

The encoding algorithm to use such as 'UTF-8'. Relevant when the type used is DEFAULT.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.password-encoder.secret=

Secret to use with STANDARD, PBKDF2, BCRYPT, GLIBC_CRYPT password encoders. Secret usually is an optional setting.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.password-encoder.strength=16

Strength or number of iterations to use for password hashing. Usually relevant when dealing with PBKDF2 or BCRYPT encoders. Used by GLIBC_CRYPT encoders as well.

org.apereo.cas.configuration.model.core.authentication.PasswordEncoderProperties.

cas.monitor.endpoints.jdbc.autocommit=false

The default auto-commit behavior of connections in the pool. Determined whether queries such as update/insert should be immediately executed without waiting for an underlying transaction.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.batch-size=100

A non-zero value enables use of JDBC2 batch updates by Hibernate. e.g. recommended values between 5 and 30.

cas.monitor.endpoints.jdbc.data-source-name=

Attempts to do a JNDI data source look up for the data source name specified. Will attempt to locate the data source object as is.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.ddl-auto=update

Hibernate feature to automatically validate and exports DDL to the schema. By default, creates and drops the schema automatically when a session is starts and ends. Setting the value to validate or none may be more desirable for production, but any of the following options can be used:

validate: Validate the schema, but make no changes to the database.
update: Update the schema.
create: Create the schema, destroying previous data.
create-drop: Drop the schema at the end of the session.
none: Do nothing.

Note that during a version migration where any schema has changed create-drop will result in the loss of all data as soon as CAS is started. For transient data like tickets this is probably not an issue, but in cases like the audit table important data could be lost. Using `update`, while safe for data, is confirmed to result in invalid database state. validate or none settings are likely the only safe options for production use.

For more info, see this.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.default-catalog=

cas.monitor.endpoints.jdbc.dialect=org.hibernate.dialect.HSQLDialect

The database dialect is a configuration setting for platform independent software (JPA, Hibernate, etc) which allows such software to translate its generic SQL statements into vendor specific DDL, DML.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.fail-fast-timeout=1

Set the pool initialization failure timeout.

Any value greater than zero will be treated as a timeout for pool initialization. The calling thread will be blocked from continuing until a successful connection to the database, or until the timeout is reached. If the timeout is reached, then a PoolInitializationException will be thrown.
A value of zero will not prevent the pool from starting in the case that a connection cannot be obtained. However, upon start the pool will attempt to obtain a connection and validate that the connectionTestQuery and connectionInitSql are valid. If those validations fail, an exception will be thrown. If a connection cannot be obtained, the validation is skipped and the the pool will start and continue to try to obtain connections in the background. This can mean that callers to DataSource#getConnection() may encounter exceptions.
A value less than zero will not bypass any connection attempt and validation during startup, and therefore the pool will start immediately. The pool will continue to try to obtain connections in the background. This can mean that callers to DataSource#getConnection() may encounter exceptions.

Note that if this timeout value is greater than or equal to zero (0), and therefore an initial connection validation is performed, this timeout does not override the connectionTimeout or validationTimeout; they will be honored before this timeout is applied. The default value is one millisecond.

org.apereo.cas.configuration.model.core.monitor.JdbcSecurityActuatorEndpointsMonitorProperties.

cas.monitor.endpoints.jdbc.fetch-size=100

Control global properties that are relevant to Hibernate, when CAS attempts to employ and utilize database resources, connections and queries.

cas.jdbc.case-insensitive=false

When choosing physical table names, determine whether names should be considered case-insensitive.

cas.jdbc.gen-ddl=true

Whether to generate DDL after the EntityManagerFactory has been initialized creating/updating all relevant tables.

cas.jdbc.physical-table-names=

Indicate a physical table name to be used by the hibernate naming strategy in case table names need to be customized for the specific type of database. The key here indicates the CAS-provided table name and the value is the translate physical name for the database. If a match is not found for the CAS-provided table name, then that name will be used by default.

cas.jdbc.show-sql=false

Whether SQL queries should be displayed in the console/logs.

If you need to design your own password encoding scheme where the type is specified as a fully qualified Java class name, the structure of the class would be similar to the following:

package org.example.cas;

import org.springframework.security.crypto.codec.*;
import org.springframework.security.crypto.password.*;

public class MyEncoder extends AbstractPasswordEncoder {
    @Override
    protected byte[] encode(CharSequence rawPassword, byte[] salt) {
        return ...
    }
}

If you need to design your own password encoding scheme where the type is specified as a path to a Groovy script, the structure of the script would be similar to the following:

import java.util.*

byte[] run(final Object... args) {
    def rawPassword = args[0]
    def generatedSalt = args[1]
    def logger = args[2]
    def casApplicationContext = args[3]

    logger.debug("Encoding password...")
    return ...
}

Boolean matches(final Object... args) {
    def rawPassword = args[0]
    def encodedPassword = args[1]
    def logger = args[2]
    def casApplicationContext = args[3]

   logger.debug("Does match or not ?");
   return ...

The following settings and properties are available from the CAS configuration catalog:

cas.monitor.endpoints.ldap.base-dn=

Base DN to use. There may be scenarios where different parts of a single LDAP tree could be considered as base-dns. Rather than duplicating the LDAP configuration block for each individual base-dn, each entry can be specified and joined together using a special delimiter character. The user DN is retrieved using the combination of all base-dn and DN resolvers in the order defined. DN resolution should fail if multiple DNs are found. Otherwise the first DN found is returned. Usual syntax is: subtreeA,dc=example,dc=net|subtreeC,dc=example,dc=net.
